Green Valley Creek
Green Valley Creek is a major tributary in the lower Russian River
Watershed. It contains critical habitat for steelhead trout, remnant
populations of coho salmon, and Chinook salmon in its lower
There are approximately 18.7 miles of blue line stream in the Green
Valley Creek Watershed, including Purrington Creek, which
contributes important summer flow to the stream system.
Green Valley Creek is the most recent stream in the Russian River drainage where some of the last wild juvenile coho were known to exist. It is currently stocked with juvenile coho each year as part of the
Russian River Coho Salmon Captive Broodstock Program.
California Department of Fish and Game (DFG) stream inventory
reports from the last decade assessed spawning and rearing habitat
in Green Valley Creek and its tributary Purrington Creek. Higher
quality spawning and rearing habitat were identified in two upper
reaches of Green Valley Creek.
The highest quality salmonid habitat in the stream system is located
above the confluence with Atascadero Creek and in the lower portion
of Harrison Creek. However, according to the 1994 stream inventory
report, sedimentation in the upper portion of the watershed has the
potential to seriously degrade higher quality habitat downstream. The
stream habitat report for Purrington Creek found that the tributary's
lower reach contained fair habitat for salmonid rearing, while its
upper reach had fair habitat for both spawning and rearing.
